One of the most important tools we have in ophthalmology is corneal topography. With this tool the ophthalmologist can literally see the refractive problems that might be present in the cornea. Corneal topography is used not only for screening all patients before refractive surgery like Lasik but also for fitting contacts, adjusting post-surgical corneal transplants, and diagnosing refractive disorders and diseases. In our clinic we primarily use the Tomey TMS-1.
Example of the topography of a cornea after Photo Refractive Keratectomy for Myopia.
This example of a patient considering Lasik showed contact lens warpage at the bottom of the cornea even though contacts had not been worn for two weeks.
One of uses many uses of topography is in diagnosing a corneal disease called Keratokonus where the cornea "cones" and becomes weak.
